這篇文章主要為大家詳細介紹了如何使用Python實現(xiàn)MP3格式轉(zhuǎn)化為wav,flac和ogg等,文中的示例代碼講解詳細,有需要的小伙伴可以參考一下

文件準備

這是我要轉(zhuǎn)化的mp3文件，我想把它轉(zhuǎn)化為wav文件，并存儲到wav之中

代碼準備

import os
import logging
from pydub import AudioSegment
from concurrent.futures import ThreadPoolExecutor
from tqdm import tqdm
 
# 設置日志記錄器
logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s')
 
class AudioConverter:
    def __init__(self, input_format, output_format):
        """
        初始化音頻轉(zhuǎn)換器類
        :param input_format: 輸入文件格式 (例如: 'mp3', 'wav', 'ogg', 'flac')
        :param output_format: 輸出文件格式 (例如: 'mp3', 'wav', 'ogg', 'flac')
        """
        self.input_format = input_format
        self.output_format = output_format
        logging.info(f"AudioConverter initialized for {input_format} to {output_format} conversion.")
 
    def convert(self, input_file_path, output_file_path):
        """
        執(zhí)行音頻格式轉(zhuǎn)換
        :param input_file_path: 輸入文件路徑
        :param output_file_path: 輸出文件路徑
        """
        try:
            # 檢查輸入文件是否存在
            if not os.path.exists(input_file_path):
                logging.error(f"輸入文件不存在: {input_file_path}")
                return
            
            # 根據(jù)輸入格式加載音頻文件
            logging.info(f"開始轉(zhuǎn)換: {input_file_path} -> {output_file_path}")
            audio = AudioSegment.from_file(input_file_path, format=self.input_format)
            
            # 導出為目標格式
            audio.export(output_file_path, format=self.output_format)
            logging.info(f"轉(zhuǎn)換完成: {output_file_path}")
        except Exception as e:
            logging.error(f"轉(zhuǎn)換失敗: {e}")
 
    @staticmethod
    def batch_convert(file_pairs, input_format, output_format, max_workers=4):
        """
        批量音頻轉(zhuǎn)換，支持多線程
        :param file_pairs: [(input_file_path, output_file_path), ...] 文件路徑對
        :param input_format: 輸入文件格式
        :param output_format: 輸出文件格式
        :param max_workers: 最大并發(fā)線程數(shù)
        """
        converter = AudioConverter(input_format, output_format)
        with ThreadPoolExecutor(max_workers=max_workers) as executor:
            # 使用進度條跟蹤批量轉(zhuǎn)換
            for _ in tqdm(executor.map(lambda file_pair: converter.convert(*file_pair), file_pairs), total=len(file_pairs)):
                pass
 
# 使用示例
if __name__ == "__main__":
    # 設置要轉(zhuǎn)換的格式，支持mp3, wav, ogg, flac等格式
    input_format = "mp3"
    output_format = "wav"
    
    # 單文件轉(zhuǎn)換示例
    input_file_path = "D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/mp3/Joel Adams - Please Don't Go (Official Music Video).mp3"
    output_file_path = "D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/wav/Joel Adams - Please Don't Go (Official Music Video).wav"
    
    converter = AudioConverter(input_format, output_format)
    converter.convert(input_file_path, output_file_path)

代碼共修改的位置一共有兩處

    input_file_path = "D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/mp3/Joel Adams - Please Don't Go (Official Music Video).mp3"
    output_file_path = "D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/wav/Joel Adams - Please Don't Go (Official Music Video).wav"

這兩處第一個是轉(zhuǎn)化MP3文件的路徑，第二處是準換結(jié)果wav文件的路徑

升級用法一

    # 設置要轉(zhuǎn)換的格式，支持mp3, wav, ogg, flac等格式
    input_format = "mp3"
    output_format = "wav"

我們可以修改此處的input和output，支持的格式有，ogg，wav，flac等等等等，也就是說，如果我想從MP3到flac那么我的代碼將會是

    # 設置要轉(zhuǎn)換的格式，支持mp3, wav, ogg, flac等格式
    input_format = "mp3"
    output_format = "flac"

只用修改對應的位置即可，對應位置在下方

升級用法二批量準換

    # 批量轉(zhuǎn)換示例
    file_pairs = [
        ("file1.mp3", "file1.wav"),
        ("file2.mp3", "file2.wav"),
        ("file3.mp3", "file3.wav")
    ]
    
    # 批量轉(zhuǎn)換mp3到wav
    AudioConverter.batch_convert(file_pairs, input_format, output_format)

批量轉(zhuǎn)換只需將 file1.MP3替換為路徑，file1.wav替換為輸出路徑

如

    file_pairs = [
        ("D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/mp3/Joel Adams - Please Don't Go (Official Music Video).mp3", "D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/wav/Joel Adams - Please Don't Go (Official Music Video).wav"),
        ("D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/mp3/Swag _ Miyauchi _ Audio.mp3", "D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/wav/Swag _ Miyauchi _ Audio.wav"),
    ]
    
    # 批量轉(zhuǎn)換mp3到wav
    AudioConverter.batch_convert(file_pairs, input_format, output_format)

為方便觀看我將（）中，的部分換行，顯示到下方

    file_pairs = [
        ("D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/mp3/Joel Adams - Please Don't Go (Official Music Video).mp3"
   , "D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/wav/Joel Adams - Please Don't Go (Official Music Video).wav"),
        ("D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/mp3/Swag _ Miyauchi _ Audio.mp3"
         , "D:/400-File/000-Project/000-Pycharm/005-CSDN_File/005-convert_music/wav/Swag _ Miyauchi _ Audio.wav"),
    ]

需要修改的位置對應到代碼處為
